A session contains the settings, data, and results associated with your application. Each session is saved in a separate file; so you can delete, move, copy, or share a session by simply deleting, moving, copying, or sharing the session file. By convention, the file extension .vp is used for Visual Profiler session files.
There are two types of sessions: an executable session that is associated with an application that is executed and profiled from within the Visual Profiler, and an import session that is created by importing data generated by the command-line profiler.
